Right Sizing Usage

Introduction

In this tutorial we will introduce Ocean VPA suggestions and present how to use it. This feature will help you define better resource requirements (based on actual consumption) in order to avoid cluster over\under provisioning, increase the cluster’s efficiency.

Prerequisites

Use VPA Guide

Step 1 – Monitoring deployment resource consumption

Ocean will collect usage metrics for all deployments in the cluster periodically, once every 5 minutes. Based on past 2 weeks of collected metrics, Ocean will calculate relevant consumption metric for each resource (CPU and Memory), and base its suggestions upon these calculated metrics.

VPA suggestions and the below mentioned graphs display data after at least 4 days of deployment metrics collection.

Open your Ocean cluster console.

Under Namespaces, click on the deployment you wish to review to find CPU Utilization and Memory Utilization charts.
